The above transmission distance is for reference only, not the basic indicator of the transmitter. The transmission distance is affected by many factors, such as what antenna is used for transmission, the height of the transmitting antenna, the surrounding obstacles, the sensitivity of the receiver, the weather, etc., which will cause great discrepancies, and the actual usage and working environment of each customer Different, it is recommended to measure. If you are not satisfied after receiving the goods, please do not confirm the receipt of the goods, please negotiate and solve them in a friendly manner. Thank you for your cooperation!
